The article analyses the implementation of the principles of environmental self-restoration and dynamic adaptability of trade enterprises. Solving the problems of introducing environmental aspects of sustainable development into the activities of trade enterprises and developing waste disposal methodologies are important tasks for the country's economy. It is offered to develop a methodology (system) of waste processing, which are formed in the process of consumption of commodity-material values in trade. The methodology includes the following factors: cost-effectiveness, social significance of disposal, safety of waste processing, resource saving, environmental reputation. The method includes several stages: analysis of the regulatory framework, the settlement and analytical stage, and the final stage - the assessment of economic efficiency. The main difference between the method and the one developed earlier is in an integrated approach to justifying the creation of a modern waste treatment system in commercial enterprises. The offered method develops the theory of economic and investment analysis, as well as the theory of making management decisions in managing the development of commercial enterprises.

The Water-Energy-Food (WEF) nexus describes the synergies and trade-offs between water, energy and food. Despite the significant attention that the WEF nexus has received in recent years, challenges remain, primarily related to gaps in integrated data, information and knowledge related to the most critical inter-linkages and their dynamics. These WEF nexus complexities and uncertainty make decision-making and future forecasting extremely difficult. Policy makers and other stakeholders are currently faced with the task of understanding longer term environmental impacts and tJhe benefits and limitations of innovations that could be potentially beneficial, such as Anaerobic Digestion as a waste solution or insect protein production. This paper describes an approach to support decision making for local-level innovations within the WEF nexus by creating a set of sustainability indicators and an accompanying interactive visualisation. The indicators were derived from stakeholder consultation processes and workshops, and they were selected to include a much broader assessment than just financial aspects when considering the viability of such innovations. By taking this bottom-up approach and placing stakeholders at the heart of the project, we produced a visualisation tool to support sustainable decision making when considering the implementation of WEF innovations. Considering other, often overlooked factors and giving greater priority to these deepens knowledge and the recognition of influential issues that in conventional processes may be overlooked. This visualisation tool is designed to support decision makers to engage in a exploration of the different interlinkages, and to be the basis of stakeholder dialogue around sustainability. The visualisation tool developed was designed to be easily modifiable in order to be updated with new insights and to include other future innovations.

Abstract Food production is connected with a negative effect on the environment as it is linked with the utilisation of natural resources such as fresh water and with the emission of greenhouse gases (GHGs). It is, therefore, very important to prevent the wastage of food at all food chain stages. Special attention should be paid to the phenomena which burden the environment in an unjustified way. One such example may be the waste of final products at the stage of retail sale objects. The purpose of the present paper was to estimate the effect of wasted food in the selected network of the retail sale on the environment with the application of water footprint indicator and CO2 emission. On the grounds of the collected data, the participation of food withdrawn from the trade, the reasons for the mentioned phenomenon and the size of the wasted food products and those donated to charities were established. Based upon such data, the level of CO2 emission and the water print of the products which have not been utilised according to their destination were estimated. In spite of the fact that the animal origin products were characterised by a small participation in the weight of the unsold food (ca. 13.34% annually), they constituted the main source of CO2 emission and water footprint estimated from the food waste. It was calculated that the annual turnover and waste of the products only in one trade network was connected with the unjustified emission of ca. 12 thousand tonnes of CO2 and 13 million m3 of water footprint.

Testo completoAbstract (sommario):
Around 6 million tonnes of edible food are being wasted (post-farm gate) in the UK each year. This fraction of edible wasted food is known as avoidable food waste. In a circular economy food is a valuable resource that must be captured at all stages of the food supply chain and, where possible, redistributed for consumption. This can prevent avoidable food waste generation, and dissipation of food’s multidimensional value that spans environmental, economic, social, technical and political/organisational impacts. While the importance and benefits of surplus food redistribution have been well documented in the global literature, there are still barriers that prevent perfectly edible food from being wasted. This study looks at the main stages of the food supply chain, and amasses the opportunities, challenges and trade-offs associated with surplus food redistribution to the UK economy. It highlights points in the food system where interventions can be made, to improve food’s circularity and sustainability potential. Stakeholder interrelations, regulatory and socio-economic aspects are discussed in relation to their influence on decreasing avoidable food waste. The main output from this work is a diagrammatic depiction of where challenges and trade-offs occur along the food supply chain, and how policy and socio-economic reforms are needed to maximise avoidable food waste prevention, and the surplus avoidable food redistribution in the food supply chain for social benefit.

Testo completoAbstract (sommario):
The start-up and step-up operation of two 16-liter, continuously operated, upflow anaerobic reactors receiving baker's yeast wastewater is presented in this thesis. The two reactors (A and B) were almost identical in construction. Reactor A was a conventional upflow anaerobic sludge blanket (UASB) reactor, and reactor B was a hybrid reactor. In addition to all the features of a UASB reactor, a fixed-film structure was installed in the mid section of the reactor B. Both reactors were operated at 35 °C and at a constant hydraulic retention time of 7 days. The waste strength, expressed in chemical oxygen demand (COD), was varied from 8 g COD liter⁻¹ (during the start-up) to 58 g COD liter⁻¹. The organic loading rate ranged from 1.1 to 9.4 g COD liter⁻¹ day⁻¹. The start-up lasted for the first 46 days. Towards the end of the start-up, methane production rates of 0.23 and 0.28 liter CH₄ liter⁻¹ day⁻¹ and COD reductions of 62.2% and 67.2% were achieved at organic loading rates of 1.1 and 1.3 g COD liter⁻¹ day⁻¹ for reactors A and B respectively. During the step-up operation, maximum methane production rates were, for reactors A and B respectively, 0.91 and 0.95 liter CH₄ liter⁻¹ day⁻¹ at organic loading rates of 5.8 and 6.4 g COD liter⁻¹ day⁻¹. In addition, reactor profiles for sludge concentration, pH, volatile fatty acids, and COD are also presented.Applied Science, Faculty of

Testo completoAbstract (sommario):
The sorption of unformulated (98% pure) and
formulated (86% pure + adjuvants) metolachlor to peat,
rubber, and steam-exploded wood was studied. The
concentration of pesticide ranged from 50 mg/L to
400 mg/L. Equilibrium concentrations for the batch
reactors were reached within 24 hr. The sorption data for
both unformulated and formulated metolachlor were best
described by the Freundlich isotherm model. Metolachlor
was preferentially sorbed in the following order:
rubber > peat > wood fibers, with removal efficiencies of
80-85%, 70-80% and 50-65%, respectively. Differences in
slopes of the isotherm lines and K values were negligible
for each sorbent-type tested for both unformulated and
formulated metolachlor. These results suggest that the
presence of surfactants did not affect the sorption
capacity of the sorbents at the concentration levels
tested. However, isotherm plots showed S-shaped curve
behavior for all of the sorbents in the presence of
unformulated metolachlor, while a C-shaped curve was seen
when the sorbents were mixed with formulated metolachlor.
This suggests that different bonding mechanisms may be involved for the sorption of unformulated and formulated metolachlor to the sorbents.
Various procedures were studied to improve removal
efficiencies of formulated metolachlor. Sorption of
metolachlor to peat was enhanced by hydrating the peat and
pre-treating the peat with HCI. Circulation of formulated
metolachlor through a rubber-packed column showed the
greatest removal, with only 6 mg/L of the initial 400 mg/L
remaining in solution. Removal efficiencies of steamexploded
wood fibers were not improved by any of the
methods investigated.

Testo completoAbstract (sommario):
Thesis (Master of Engineering in Chemical Engineering)--Cape Peninsula University of Technology, 2018.The production of biodiesel is an energy and water intensive process. The wastewater that is produced during this process is high in concentrations of COD, BOD, FOG and various other contaminants. Since it contains low levels of nutrients, it is difficult to degrade using natural processes such as conventional activated sludge wastewater treatment. The discharge of untreated biodiesel wastewater also raises serious environmental concern. It interferes when remediated with biological processes and results in additional costs during the production of biodiesel when penalties and fines are applied. Conventional treatment processes are not capable of treating contaminants and pollutants in biodiesel to satisfactory concentrations and hence advanced treatment processes are necessary. In this research, a lab scale integrated treatment process was used to investigate the successful reduction of contaminants, in particular COD, BOD and FOG. The integrated treatment process used in this study consisted of three consecutive steps; acidification, electrochemical oxidation and adsorption using chitosan as an adsorbent. The electrochemical oxidation process with IrO2-Ta2O5/Ti anodes was applied to treat biodiesel wastewater. Different operating conditions were tested to establish favourable conditions. The current density applied as well as the concentration of NaCl as the supporting electrolyte greatly affected the process. A NaCl concentration of 0.08M was deemed sufficient, whereas a current density of 1 mA/cm² showed superior performance compared to lower or higher current densities. Adsorption of pollutants in biodiesel wastewater was investigated using Chitosan as the adsorbent. Various chitosan concentrations, initial pH of the wastewater and repetitive adsorption stages were investigated. It was discovered that all three operating conditions greatly affect the performance of the process. The three consecutive adsorption stages using a chitosan concentration of 4.5 g/L at a pH of 2 resulted in the highest pollutant removal. It was observed that the integrated treatment process could reduce COD, BOD and FOG levels by 94%, 86% and 95% respectively. This concludes that the treated effluent complies with local industrial effluent discharge standards, which could be disposed safely without further treatment.

Fundação Araucária; CAPESAs indústrias alimentícias utilizam considerável volume de água para suprir a demanda de processos. Devido a isso, observa-se um grande volume gerado de efluentes que necessitam ser tratados para garantir o destino final adequado. Tendo em vista a crescente escassez de água, procedimentos de racionalização do uso da água e o reúso de efluentes tratados surgem como soluções para estes problemas. A aplicação de processos de separação por membranas no tratamento de efluentes da indústria alimentícia para reúso apresenta-se como um processo de tratamento avançado apropriado. Deste modo, o objetivo deste estudo foi avaliar a utilização dos processos de separação por membranas como tratamento avançado de águas residuárias agroindustriais provindas de um abatedouro e frigorífico de suínos, da região oeste do Paraná, visando à possibilidade de reúso destes efluentes. Para isso, foi necessário: realizar a caracterização físico-química dos efluentes agroindustriais; avaliar o emprego de microfiltração, ultrafiltração, e microfiltração seguida de ultrafiltração em diferentes condições operacionais de pressão aplicada à membrana, e avaliar a qualidade do efluente obtido pelos processos de separação com membranas, considerando o atendimento das exigências técnicas, legais e sanitárias para diferentes usos industriais. Os resultados mostraram que os processos de separação por membranas apresentaram, de uma maneira geral, uma sensível melhora na qualidade do efluente final quando comparados com o atual sistema de pós-tratamento empregado pela indústria (flotador físico-químico), que promove eficiências de remoção nas faixas oscilantes de 3% a 29%, 44% a 70%, 40% a 46% e 50% a 58,5%, aproximadamente, para os parâmetros sólidos totais voláteis, turbidez, nitrogênio amoniacal e DQO, respectivamente. A microfiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (51% - 64%), turbidez (83% - 99%), nitrogênio amoniacal (21% - 24%) e DQO (64% - 72%). A ultrafiltração apresentou as seguintes faixas de eficiência de remoção, aproximadas: sólidos totais voláteis (23% - 51%), turbidez (87% - 99%), nitrogênio amoniacal (54% - 69%) e DQO (77% - 85%). A realização do ensaio de microfiltração seguido de ultrafiltração nas melhores condições experimentais investigadas obteve resultados satisfatórios na remoção de aproximadamente 97% para a turbidez, 17% para os sólidos totais voláteis, 67% para a DQO, 38% para o nitrogênio amoniacal, 96% a 99,95% para os coliformes termotolerantes e 93 a 99,69% para os coliformes termorresistentes. Com o aumento da pressão para a microfiltração e ultrafiltração foi obtido maior fluxo permeado e melhor qualidade do efluente final. Embora os efluentes tenham proporcionado distintos valores de fluxo permeado, foram obtidas curvas de desempenho bastante semelhantes, caracterizando-se por uma queda do fluxo permeado nos primeiros minutos de filtração, seguido de um período onde ocorre declínio gradual, com uma tendência ao equilíbrio. De acordo com os requisitos físico-químicos e microbiológicos mínimos exigidos para o reúso de efluentes tratados, a microfiltração e a ultrafiltração atenderam alguns dos parâmetros monitorados, alcançando a qualidade exigida para o reúso em torres de resfriamento, lavagem de pisos, irrigação de áreas verdes, lavagem de veículos, proteção contra incêndio e descarga sanitária.
The food industry uses large volumes of water to meet the demand processes. Because of this, there is a large volume of generated waste that need to be addressed to ensure proper final destination. In view of the growing scarcity of water, the use rationalization of procedures of the water and the reuse of treated effluent arise as solutions to these problems. Application of separation processes by membranes in the treatment of wastewater for reuse food industry presents itself as an appropriate advanced treatment process. Thus, the aim of this study was to evaluate the use of membrane separation processes as advanced treatment of agroindustrial wastewater stemmed from a swine slaughterhouse, the western region of Paraná, aiming at the possibility of recycling these effluents. For this it was necessary: to define the physical-chemical characterization of the agro-industrial effluents; evaluate the use of microfiltration, ultrafiltration, microfiltration and ultrafiltration then under different conditions of pressure applied to the membrane, and evaluate the quality of the effluent obtained by separation processes with membranes, considering the care of the technical, legal and health requirements for different uses industrial. The results showed that membrane separation processes presented in a general way a considerable improvement in final effluent quality compared with the current tertiary treatment system used by the industry (physicochemical flotation) which promotes removal efficiencies in oscillating ranges from 3% to 29%, 44% to 70%, 40% to 46%, 50% to 58.5%, approximately, for the parameters: total volatile solids, turbidity, ammonia nitrogen and COD, respectively. Microfiltration had the following removal efficiency ranges, approximate: total volatile solids (51% - 64%), turbidity (83% - 99%), ammonia nitrogen (21% - 24%) and COD (64% - 72%). Ultrafiltration showed the following removal efficiency ranges, approximate: total volatile solids (23% - 51%), turbidity (87% - 99%), ammonia nitrogen (54% - 69%) and COD (77% - 85%). The completion of the test microfiltration followed by ultrafiltration under the best experimental conditions investigated achieved satisfactory results in the removal of approximately 97% for the turbidity, 17% total volatile solids, 67% for COD, 38% for ammonia nitrogen, 96% to 99.95% for thermotolerant and 93 to 99.69% for the heat-resistant coliforms coliforms. With increasing pressure to microfiltration and ultrafiltration permeate flux was increased and better quality of the final effluent. Although the effluents have provided separate permeate flow rates, very similar performance curves were obtained, characterized by a drop in permeate flux during the first minute filtration followed by a period where there is a gradual decline, with a tendency toward equilibrium. According to the physicochemical requirements and minimum microbiological required for the reuse of treated wastewater, microfiltration and ultrafiltration attended some of the monitored parameters, achieving the required quality for reuse in cooling towers, floor washing, irrigation of green areas , washing vehicles, fire protection and sanitary discharge.

Resumo: O Brasil produz anualmente 30 bilhões de litros de etanol de cana de açúcar com previsão do Ministério de Minas e Energia de atingir 36 bilhões de litros em 2024. A vinhaça é o resíduo líquido, rico em potássio e matéria orgânica que resulta da destilação do etanol, na proporção de 10 a 15 litros de vinhaça para cada litro de etanol. Disposto indevidamente, pode trazer sérios riscos para o ambiente devido ao alto potencial poluidor. Os estados de São Paulo, Paraná e Mato Grosso do Sul, possuem normas específicas sobre disposição desse resíduo, mas não atingem por completo o objetivo de controlar e mitigar os problemas, pois a disposição final da vinhaça se resume unicamente na fertirrigação sem qualquer outro tratamento. No presente trabalho, realizado no Laboratório de Biomassa do Departamento de Engenharia Rural da Faculdade de Ciências Agrárias e Veterinárias da UNESP de Jaboticabal, analisou-se a biodigestão anaeróbia da vinhaça, caracterizando-se a produção de biogás e a redução do potencial poluidor. Para tanto, foram efetuados estudos de viabilidade técnica da biodigestão anaeróbia da vinhaça analisando os parâmetros: neutralização do pH da vinhaça, utilização do reciclo e estabilização da temperatura da vinhaça. Para os três parâmetros citados foram registrados e analisados dados referentes a: produção de biogás (m3), composição do biogás (% de CH4 e CO2) e redução do potencial poluidor da vinhaça após biodigestão anaeróbia (DQO). No que diz respeito a produção do biogás, os resultados considerados relevantes foram na correção do pH (aumento de 97,5%) e no aquecimento do afluente (aumento de 79%). Em relação a composição do biogás, obteve-se, aumento de 9% de metano redução de 3,6% de dióxido de carbono quando se aquece o afluente. Quando se utiliza reciclo a redução de DQO aumentou em 50% e o aquecimento do ...
Abstract: The Brazil annually produces 30 billion liters of ethanol from sugar cane with the Ministry of Mines and Energy forecast to reach 36 billion liters in 2024. The stillage is the liquid waste, rich in potassium and organic matter resulting from the distillation of ethanol in the proportion of 10 to 15 liters of vinasse per liter of ethanol. Willing improperly, can pose serious risks to the environment due to the high pollution potential. The states of São Paulo, Paraná and Mato Grosso do Sul, have specific rules on disposal of this waste, but do not reach completely in order to control and mitigate the problems because the final disposal of vinasse comes down solely in fertigation without any other treatment . In this study, conducted at the Laboratory of Biomass Department of Rural Engineering of the Faculty of Agricultural and Veterinary Sciences of Jaboticabal UNESP, analyzed the anaerobic digestion of vinasse, characterizing the production of biogas and reduce the pollution potential. Therefore, technical feasibility studies of anaerobic digestion of vinasse were made by analyzing the parameters: pH neutralization of vinasse, use of recycling and stabilization of vinasse temperature. For the three mentioned parameters were recorded and analyzed data for: biogas production (m3), biogas composition (% CH4 and CO2) and reduced pollution potential of vinasse after anaerobic digestion (COD). As regards the production of biogas, the results were considered significant at pH correction (increase of 97.5%) and heating the influent (79% increase). For biogas composition was obtained, an increase of 9% methane 3.6% reduction of carbon dioxide when heated affluent. When COD reduction using recycled increased by 50% and heating affluent allowed increased the reduction by 62%, demonstrating the technical feasibility of this study. To determine the economic feasibility ...

In today’s global business environment, logistics has become one of the key determinants of sustainable competitive advantage. In the context of sustainable project management, every project will have to embrace a sustainable logistics system. Port and maritime logistics is classified as the most significant logistics system since it is considered to be the backbone for facilitating global trade. Around 80% of the world trade by volume, and 70% by value, is done by sea and is managed by seaports across the globe. It is evident that managing the pressures of sustainability is one of the critical challenges for creating value and ensuring growth across all businesses. Port and maritime industry is required to ensure high level of accountability and transparency on sustainability concerns including waste management, climate change and global warming, energy efficiency, employee health, safety and security, impacts on local society and coastal and local environmental health. Because of the global nature of the port and maritime sector, it encounters more challenges in improving sustainability performance. This chapter covers sustainable port and maritime logistics. It starts by presenting an overview of logistics, supply chain management and maritime logistics. The second section discusses sustainability in the context of supply chain and logistics management. The third section explicates green port and maritime logistics aspects. The fourth identifies sustainability issues and introduces an integrated framework for sustainable port and maritime logistics. It wraps up with a brief section on suggested areas for future research.

Seaports are important factors in global economies since most of the global trade is operated through maritime sector. Economic importance of seaports can be observed from various positive effects they produce for the area where they are located. At the same time, seaport activities create negative effects on the environment such as marine, air and soil pollution, waste production and noise generation that affect the health and quality of life of people. This paper analyses the possibility of achieving sustainable development of seaports through the development and implementation of innovations. The implementation of innovations in seaports affect the success of their operations, reduces business costs and creates conditions for maintaining a competitive position on the market; thereby affecting the economy as a whole. Moreover, innovations reduce negative effects on the environment thus affecting the ecological aspect and improve the quality of life of citizens, thus affecting the social aspect. The results of the research indicate that innovations in the maritime sector are mostly focused on the existing markets and include a discounted process of small improvements in the areas of vessel design and construction, fuel technology and port infrastructure. However, the development possibilities of seaports can also include innovations that are more focused on information and communication technologies (ICT). Innovations can address economic, social and environmental concerns and can give alternative guidelines for achieving sustainable development of seaports.

Responding to a sustainable production is an imperative that is gaining more and more relevance in the definition of specific programs and strategies at national and international level. This urgency leads towards zero waste and circular models and processes that minimize the extraction of resources from the biosphere and do not create waste; instead, when the waste of natural or anthropogenic transformations cannot be avoided, their valorization as resources must be carried out. The development of integrated supply chains, knowledge transfer between different disciplines and the dialogue between research and industry becomes fundamental for the achievement of these objectives. Existing studies in the literature regarding the agri-food production chain in Italy show that the sector, whose environmental impacts are by no means marginal, is fragmented in many small production companies; an interesting and critical aspect at the same time since the generation of waste is not accompanied by an appropriate dissemination of data at a quantitative-qualitative level and there is no clear regulatory framework available on alternative management and valorisation methods. Design, given its natural inclination to transversality, allows to trace scenarios in which to configure, through interdisciplinary approaches, the sustainability models that are intended to be covered in this contribution. Moreover, its methods and tools allow to develop a critical thinking starting from the very early designing phase. The paper addresses the valorisation of agro-industrial waste in a circular and systemic perspective through the presentation of a review of case studies from the textile supply chain, which is one of the most relevant for Italian industry.Due to its disastrous environmental impact, the global textile industry is today the subject of extensive research aimed at the development of innovative materials and processes in order to overcome the traditional linearity of the textile supply chain. The negative impacts of the textile industry are distributed along the entire value chain and are mainly attributable to greenhouse gas emissions -for which the textile industry represents the fifth manufacturing sector- consumption and pollution of water resources and the production of textile waste. In particular, the production of synthetic fibers, which is estimated to be almost two thirds of the global fiber production, is associated with a high use of non-renewable resources and emissions, which derives from the extraction of fossil fuels. In this sense, the valorisation of agro-industrial waste as secondary raw materials and new sustainable inputs for the textile supply chain, represents an opportunity not yet fully explored, in particular as regards the development of a new generation of fibers, yarns and eco-compatible fabrics alternative to the materials currently in use. Bio-based wastes and by-products from agri-food industry could as well present enormous potential for valorisation in the textile finish due to their intrinsic properties (antimicrobial, prebiotic, antioxidant activity, among others). At present, nevertheless, textiles from agro-residues do not completely meet the requirements to make them an attractive replacement for conventional fibre sources. Future research should therefore focus on identifying new agro-residue based blends that offer both performance and sustainability, adopting a systemic design approach based on interdisciplinary and interconnections as a strategy for innovation.

Construction industry creates an environment for people's lives. On the other hand, construction activities have a negative impact on various aspects of the environment. It consumes natural raw materials, significantly contributes to carbon footprint, waste, etc. Appropriate choice of constructional, material, technical, technological and environmental parameters of buildings can partially reduce this negative impacts. By designing, implementing and using wood-based constructions it is possible to reduce the negative impact in the area of construction waste generation. Currently, the construction market offers a large number of construction systems of wooden buildings, which have both strengths and weaknesses. In this paper are identified construction systems of wooden buildings offered on the Slovak construction market. The aim of the paper is a detailed identification of construction waste generation during the realization of particular wooden structures and monitoring of waste generation in production factory (off site) and on construction site (on site) during the construction of wooden buildings. Based on the obtained information, the individual construction systems of wood-based constructions are compared in terms of construction waste generation

Abstract With the increasingly stringent national environmental rules, waste produced in drilling and completion process is forbidden to be discharged into the Bohai Bay or reinjected into the formation. The current disposal method of drilling and completion waste in Bohai Oil field has some problems such as high cost, low efficiency and high HSE management and control risk. Faced with these problems, drilling and completion waste reutilization and zero discharge technology has been developed and applied in this region. In order to reutilize drilling and completion waste which include cuttings circulated from formation, wasted drilling and completion fluids, the following aspects are carried out: Firstly, drilling platform is upgraded to meet the zero discharge requirement: solid control system is modified, cuttings closed transfer system and cuttings treatment system are equipped on the platform to collect and dispose the waste. Meanwhile, recovery and disposal capacity to support different spud drilling are assessed: cuttings transport capacity is up to 15m3/h, which can meet the highest requirements of 12-1/4″ hole drilling when ROP is up to180m/h. Secondly, the well profile is downsized to reduce the production of cuttings, mud and other wastes from the root, which can also improve efficiency and yield cost. The field application shows that the amount of the waste has been reduced by 41.39%, 39.86% and 41.52% in first, second and third spud drilling, and average ROP is 35%, 28%, 42% higher than similar wells drilled before. Lastly, in drilling and completion fluids system optimization and reutilization aspects, environmentally friendly drilling and completion fluids with low solid content are developed. The experiment shows that the properties of the liquid phase after solid-liquid separation can be reused, and the solid phase with low water content is easy to pack and transport back to land. Drilling and completion waste reutilization and zero discharge technology introduced in this paper has been successfully applied in more than 40 wells, and the volume of waste drilling fluid is reduced by 80%, which is a trade-off between zero discharge and well construction cost. This technology can also be applied in other offshore oilfield which is inevitable as the environmental rules become more and more strict.
